SIASUN New Energy Vehicle Trunk Battery Pack Tightening (GCR20)

A car trunk is a small room with an awkward door, and the bolts inside it still have to be tightened correctly on every vehicle while the line keeps moving. SIASUN New Energy Vehicle Trunk Battery Pack Tightening (GCR20) answers that problem with a collaborative robot that has been given vision and a tightening tool, so the work happens in the tight space without a person leaning into it.

Background

The company and the DUCO robot line

SIASUN builds robots for factories and logistics, and its catalog on this store runs from heavy-duty mobile robots to electronics automation. The robot behind this application is the SIASUN DUCO GCR20, a member of the DUCO collaborative robot family. Collaborative robots are designed to share a work area with people instead of being locked behind a cage. That makes them a natural choice on assembly lines where operators and machines already stand side by side.

For this project the GCR20 is fitted with a vision system. The project was analyzed as a whole before the robot was chosen. The GCR20 won the job for its large load, its high flexibility and its light weight, and with vision added it became a tightening expert. It takes up the work of tightening the trunk battery pack on the fly with the line. You can see the wider range in the SIASUN category.

Positioning: a tightening cell built for a cramped space

The difficulty of this application is geometry. The working space in the trunk of the car is very small, so the flexibility of the robot matters a great deal, and the end tightening tool has to be more compact than it would be on an open bench. This is not a general bolt-driving demonstration. It is a solution shaped around one hard location on a new energy vehicle.

Two further ideas define the product. The first is vision. The combination of robot and vision enables secondary positioning of the battery pack tightening point. The robot does not simply run to a taught position; it checks where the tightening point actually is and corrects. The second is safety. The active-passive safety system of the DUCO collaborative robot works in tandem with people, occupies a small location and removes the need for safety fencing.

In general, battery pack fastening is one of the steps where plants look hardest at automation. The bolts hold a heavy, valuable component to the vehicle body, so every joint matters, and the people who do the work by hand do it in uncomfortable postures. A collaborative robot with vision is one way to take the strain off the operator while keeping the quality of each joint under control.

What makes the GCR20 suited to a trunk battery pack?

Three qualities were named when the project was analyzed: large load, high flexibility and light weight. Each answers a different part of the job.

The load of 20 kg matters because tightening is not a light task. It gives the GCR20 the ability to tighten with high torque and guarantees tightening quality. The robot carries the tool and holds its position against the force of the work.

Flexibility matters because of the trunk itself. The space is very small, and a robot that cannot bend its arm into awkward poses is of little use there. The light weight of the robot supports this, since a lighter arm is easier to place beside a moving vehicle body and easier to work with in a confined cell.

Vision completes the picture. A vehicle on a moving line never stops in exactly the same place twice, and a battery pack can sit slightly differently from one body to the next. Secondary positioning lets the robot locate the tightening point again before it works, which improves tightening speed and yield. For a buyer, yield is the figure that decides whether automation pays: fewer missed or poorly seated bolts means less rework further down the line.

Does this robot need safety fencing?

No. The active-passive safety system of the SIASUN DUCO collaborative robot is able to work in tandem with people, occupying a small location and providing safety for site staff while eliminating the need for safety fencing.

This is more important than it may sound. Automotive floors are crowded, and every square meter given to a fence is a square meter that cannot be used for production. A cell without fencing keeps the footprint small and lets staff move around the station for supervision, changeover and maintenance. As with any robot installation, the safety assessment of the finished cell remains the responsibility of the integrator and the plant.

Who is the SIASUN GCR20 tightening solution for?

The first group is the vehicle maker or battery pack assembler that already builds new energy vehicles and wants to automate a fastening step that is physically awkward for people. Working inside a trunk means bending, reaching and holding a tool in a poor position for a full shift. Giving that task to a robot removes a repetitive strain from the line.

The second group is the system integrator. A project like this needs a robot, a vision system, a compact tightening tool and a plan for the line. Integrators who put together tightening cells will find in the GCR20 a collaborative base that has already been used for this kind of work on the fly with the line.

The third group is the engineering team that is weighing fixed automation against a flexible robot. Where the joint location is hard to reach and the space is small, a collaborative robot with vision offers an alternative to a dedicated machine. Teams in the Caribbean that supply or assemble vehicle components, or that plan new energy vehicle capacity, can request a quotation and talk through the line layout with us.

If your needs are material transport rather than tightening, the SIASUN range includes mobile robots, which you can reach through the SIASUN category. This page is for the tightening application.

What is the SIASUN GCR20 used for?

1. Trunk battery pack tightening. The main job: tightening the battery pack in the trunk of a new energy vehicle on the fly with the line.
2. Tightening with high torque. The 20 kg load lets the robot carry out tightening that needs strong force while keeping the tightening quality.
3. Vision-guided positioning. Robot plus vision gives secondary positioning of the tightening point before the bolt is driven.
4. Work in confined spaces. The flexible, light arm and a compact end tool let the robot operate in the very small space of a trunk.
5. Working beside staff. The active-passive safety system lets the robot share the station with people.
6. Fence-free cells. Because no safety fencing is needed, the cell takes up a small location on the production floor.

Frequently Asked Questions

Which robot does this solution use?

It uses the SIASUN DUCO GCR20 with a vision system. The robot does the tightening work on the trunk battery pack on the fly with the line.

What load does the GCR20 offer?

The load is 20 kg. This lets the robot tighten with high torque and guarantees tightening quality.

How does the vision system help?

Robot plus vision enables secondary positioning of the battery pack tightening point. This improves tightening speed and yield.

Is safety fencing required?

No. The active-passive safety system works in tandem with people, occupies a small location and removes the need for safety fencing.

Why is the trunk such a hard place to automate?

The working space is very small. The robot must therefore be flexible, and the end tightening tool must be compact.

What are the tightening torque and the reach?

Those figures are not part of the data we hold for this product. Ask for them in your quotation request.

Where can I buy the SIASUN GCR20 tightening solution and what does it cost?

You can request it through this page. The cost depends on your line and configuration, so we provide a quotation instead of a fixed price.
